ELECTRIC TIME-SWITCH.

Specification of Letters Patent.

Patented Oct. 9, 1906.

To It whom it may concern.-

Be' it known that I, CHARLES H. VAN

' SLYCK, a citizen of the United. States, residing at Philadelphia, county of Ihiladelphia, State of Pennsylvania, have invented certain new anduseful Improvement: in Electric Tillie-Switches, of which the following is a specification.

This invention relates to time-switches for electric circuits, and a switch constructed in accordance therewith is adaptedto have its opening and closing movements controlled by a chronometer in order to regulate automatically the supply of current to various translating devices at predetermined. inter-- vals.

As an illustrative example one of many structures in which the invention may be embodied is shown in the drawings, of 20 which- Y I Figure 1 is a full face view of the interior of the casing, showin the operating mechanism.

' Figs. 2 and-3 are ateral and plan views, re-

speotively, of the same; and Fig. 4, is the circuit-diagram.

Certain features of the invention are not limited in their application as embodiments of a time-switch as above described, but may be embodied in any electrically-operated'switch and are useful in still other relations.

A-is a chronometer or clock-movement ac- 'u ated in any suitable manner, as by a spring '1} electricity, and insulated from the workcircuits. :Ihe working spindle of A makes'only one complete rotation in twenty- "four-hours. thumb-screw 1 holds springs to the rotating-'chronometer member at selected angles, of the springs being thereby adapted to"fclose and the other to openthe working; circuit at predetermined I the frame intervals. Each-spring is successively put under tension by engagement with a rigid -pin C, and when it is carried past the pin it impinges aghainst the lever D, pivoted at 2 to whereupon the roller 3, supported in a dependent of the lever below the pivot moves up the incline of the inverted V of the spring 4 This spring is secured to the frame F, and the contact E, carriedby and insulated from the lever D, is, snapped into enga ement with the contact E, which is carried by andjnsulated from the frame F and connected throu h the magnet-coil H to one pole Q, Fig. 4, o theswitch, to which is connected one side of the generator. Any number of switch-actuating electromagnets could be connected in series in the circuit thus established. The contact E is electrically eonnected to another pole Q, Fig. 4, of the switch, to which pole is connected a lead from the other side of the generator G. If thesecon'taots E and E close a circuit derived either from the generator-circuit or an auxiliary sourcecut out later, the coil H will be energized and the core I drawn down against the tension of the adjustable spring 4* on the lever J, which is pivoted at 5. yPiv-' oted to J at 6 is a link K, which is pivoted at its other end 7 to a supporting-rod P, loosely mounted on a rotatable spindle 9. A pawl L is pivoted at 10 to the rod P, and when the link K is depressed the pawl moves the ratchet-wheel M, secured to the s indle 9, one notch downward on the left, w ereupon aspring-dog 11 enga es with a next or on notch in a stop-whee N, also secured to the spindle 9. A disk 0, of insulating material, Fig. 3, is secured to the spindle 9 and carries a series of pins of good conducting material arranged in a circle. Referring to Fig. 4, it may be seen that with the spindle 9 at this point in its rotation two pins make contact simultaneously, the one beneath the plane of the sprin 7 -contacts engaging with the springcontact connected to one side of the line,

and the spring-contact R, connected to one side of the circuit of the translating devices X, and the other pin above, the plane of the spring-contacts engaging with the springcontact Q, connected to the other side of the line, andthe spring-contact R, connected to the other side of the translating-device circuit. The latter circuit is now closed.

Adjustabl y mounted on the ma et-core I by means of a set-screw U, as s own, is a sleeve S, carrying a pin or dog T, which is adapted to engage the lever D in the downpressing the spring 4, which snaps it back and holds the contact against the pin C. The core I will now rise un er the tension of the spring 4, as the coil H is no longer energized, and the apparatus is ready for the operation of ope'ning the switch, which is accom lished in a similar manner to that describe for its 5 closing by the engagement of the other spring B with the pin C. At the end .of this operation the sprin -dog 11 engages in the next or off notch 0 the stop-wheel N, and, Fig. 4, all the pins P are separated from the spring switch-contacts. I

In Fig. 1 is shown the mode of connecting the outside circuits to the apparatus, which are not, as shown for clearness in Fig. 4, di-

1 tacts. An insulating-strip 12 is secured to pieces 13, each provided with binding-posts,

one-for the-outside circuit and one for the rent in the-line or not, and they remain in contact until current-is-turned on, when theswitch is openedor closed, as has been predetermined.- If the current is cut off at the station, the switch will remain in the position to which it has-previously been moved and at the predetermined time the contacts E andE Wil engage, and then the switch will be moved to the new position soon as current is turned on.

WhatI claim as new, and desire to secure by Letters Patent of the United States, is'- 1.
